IMPROVEMENT IN EARTH-PULVEEIZER AND SEEDER COMBINED.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CARMAN WILSON, of Stamford, Fairfield county, Connecticut, have invented a new and useful Earth-Pulverizer and Seed-Sower Combined; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure 1 is a plan or top view ofmy invention.

Figure 2 is a longitudinal vertical section thereof, taken on the plane of the line we, figQl.

Similar letters of reference indicate corresponding parts in both figures.

The nature of' this invention consists in an earth-pulverizer, having a rotary lump-breaker arranged in the forward part of a toothed frame, of novel construction; it consists, also, in the combination therewith of a revolving seed-sowing device.

A'designates a quadrilateral frame, in the forward part of which a roller, B, is journalled. This roller is studded with teeth a a, which, in the present instance, are arranged spirally around it, but which may be arranged in a line parallel with the length thereof if desirable. Across the frame A. there are secured two beams CC. To the beam 0, at a point about midway of its length, there is securedthe apex of a V-shaped frame, D, whose legs are secured at the points of junction of the beam Cand the frame A; and to the beam C, at a point about midway of its length, there is secured the apex of a V-shaped frame, E, whose legs are secured at the rear corners of the frame A. These frames D E are provided with a number of teeth, a, similar to ordinary barrow-teeth, and so also are the cross-beams O C and the rear side or strip of thc frame A provided with similar-teeth. F is a revolving cylinder mounted in hearings on the frame near the cross-beam C. This cylinder has a door, 6, on one of its sides, through which to deposit seed in the cylinder, and it is perforated with holes sufficiently large to allow the kind of seed to be sewn to drop out ofit. The oylinder shaft is provided with a pulley, d, on one of its ends, which is connected by a belt, c,.to a pulley, f, on the endof the roller-shaft or journal, by means of which a rotary motion is imparted to the seed-cylinder by the roller B Instead of pulleys and belts, cog gearing may be employed, or any other suitable mechanism, for giving the cylinder the required motion for throwing out and scattering the seed.

The operation is as follows: As the machine is drawn along the toothed roller B revolves and knocks the lumps of earth in pieces. The teeth of the V-shaped frame D then pulverize it; they also tend to throw or guide ofl on either side of the machine loose sods and stones which are too large to pass between the teeth. The seedsowing cylinder then drops the seed, and the teeth of the V-shaped frame E arid of the rear side of the frame A further pulverize the earth and cover up the seed. It will be observed that the earth-p1ilverizing device can be used with or without the seed-sowing cylinder; and I will remark in this connedtion that it does its work in a very superior manner.

I am aware of a harrow having a toothed roller journalled in its frame, and teeth all around it; I do not, therefore, claim the combination of a roller with a barrow-frame.

What I claim as my invention, and desire to secure by Letters Patent, is I 1. The combination of the toothed roller and harrow-frame, when so arranged that whenever the machine is in proper position to operate upon the ground the roller shall be in advance of the harrow, substantially as herein specifiedi 2. In combination with such earth pulverizing device, I claim the revolving seed-sowiug cylinder F, constructed and operating substantially as herein specified.
